Valve mechanism with applicator tip for cosmetic containers

ABSTRACT

VALVE MECHANISM WITH APPLICATOR TIP FOR COSMETIC CONTAINERS, in particular for compressible tubes, comprises a lid-like mounting base ( 1 ) with external means ( 2 ) for coupling the base in a liquid-tight manner to the bottleneck ( 3 ) of an usual compressible container ( 4 ), and with internal means ( 5 ) which form a passage ( 6 ) for the product and is also integral part of a valve ( 7 ) sliding upwards and downwards, with the lower end oriented to open and close the passage ( 6 ), while the upper end is centered inside a sleeve ( 9 ) which receives through its top the base of an applicator tip ( 9 ) into its inner part, and its external part receives a cap ( 10 ) that surrounds the applicator tip ( 9 ), the circular base of the cap being coupled to rotate inside the sleeve ( 8 ), combined with an actuation mechanism ( 11 ) formed in the two parts for moving upwards and downwards the valve ( 7 ) for opening and closing the passage ( 6 ) for the product, allowing or preventing the flow of the latter to the applicator tip, which is shaped like a finger, and in which the product accumulates in the desired quantity to be applied to the user&#39;s body.

FIELD OF THE INVENTION

More particularly, this invention refers to a mechanism that consists ofan intermediate assembly between a container and an applicator nozzle.On its lower side, the assembly presents the means for being connectedin a generally usual container such as a compressible tube, for example,containing a fluid that flows easily, being a liquid, oil, cream, pasteor powder, such as a cosmetic or a drug, while on the upper side it canbe fitted with different applicator tips, notably those whose ergonomicsare intended for application around the eyes or lips. The mechanism isendowed with means that combine with the applicator tip and with just ashort 90° turn, an internal valve system closes or opens the productflow, allowing it to flow with excellent quality control to theapplicator tip that in turn also includes another product outflowcontrol valve, whereby a desired quantity thereof may be delivered onthe surface of the applicator tip that in turn presents variablegeometry, adapting to the anatomy at the place where the product isbeing applied, on the eyes or lips.

The invention thus addresses a mechanism with at least two types ofapplicator nozzles for use on different types of substantially flexiblecontainers, whose contents are extracted in largely the same manner ascosmetics with different stages of fluidity, normally packed incompressible tubes and all types of filled recipients that mayfacilitate and allow stringent control of the quantity of product to beapplied, as occurs with topical products, for example, either cosmeticsor drugs.

STATE OF THE ART

There are countless containers available today with resources similar tothose mentioned above, as addressed by the following documents, forexample: CN103826753A, U54987911, U55960802, U56745781, U56793431,U57309184, U57824124, U58226319, U.S. Pat. No. 8,662,776, U58714857,U52013/108349, US2002/0014254, US2002/0090247, U52003/0057236 andU520030057236. Logically, each document describes a specific type ofconstruction for the application of a product, always in order to offera more efficient way of handling, controlling and applying the product.

There is not the slightest doubt that the mechanisms known for thepurpose described above are sufficient for the product to be appliedcorrectly; however, mechanisms that work with internal valves, althoughefficient, could be improved considerably, it has been noted, as many ofthem use springs, spheres and all sorts of mobile mechanical componentsthat result in a final mechanism that is substantially complicated andalso with the delivery of the product at the end of the tip notoccurring as desired, consequently becoming an assembly that isdifficult to manufacture, in terms of the fabrication of the componentsas well as their final assembly, thus significantly increasing the coststhereof, and even so without stringent control of the amount of productdispensed and, in some cases, with the residual pressure of thecontainer resulting in minor drips or leaks, with wasted product.

OBJECTIVES OF THE INVENTION

To provide two separate valves, one in the mechanism and one at theapplicator tip. The first valve is a mobile component combining a fixedstopper and a small tubular plunger that in turn is the first passagefor the product, and is also mobile in order to move axially towards oraway from the stopper, resulting in the leakproof closing or opening ofits central passage. This movement results from the fact that suchplunger has two radially opposed follower studs supported on keyways or“cams” that are engaged through these pins with the lower cylindricalrotating part of the applicator tip, whereby 90° turns in a clockwise oranti-clockwise direction establish an upward and downward movement ofthe hollow plunger, allowing or halting the flow of the product into theapplicator tip. With an anatomical fingertip shape, the entire contactarea of the latter consists of an elastomer layer on which a smallinternal pouch is formed that in turn serves as a “balloon” thataccumulates a certain amount of product and remains static as long asthe container is not pressed, at which time the pressure in the pouchincreases sufficiently for a strategic valve opening in the digitalpart, in the form of a small slot that can open and allow the controlledoutflow of a desired quantity of the product, which is in turn deliveredexactly on the surface described as “fingerlike”, because it resemblesthe tip of the forefinger. At this stage, the applicator tip is ready tobe rubbed lightly over the part of the body, the eyes or the lips, wherethe product is applied efficiently, with no waste.

In the applicator tip, its elastomer layer that forms a secondvalve-controlled outlet may have an assortment of shapes, depending onthe possibilities of its fabrication process, injected, heat molded orvulcanized, always in order to facilitate the application of creams,gels, powders and any solids or semi-solids, ensuring that they areapplied correctly as this elastomer layer may be shaped in compliancewith the specific needs of the area to be treated, with maximumapplication control and no waste, with the proper amount dispensed inthe desired volume of product as defined by the user when pressing thecontainer.

The applicator tip is valve-controlled because its elastomer layerpresents at least one outlet defined by a slot whose dimensions may beadjusted, according to each product and its density, viscosity, surfacetension and additives altering the formulation characteristics andconsequently the product flow, compliant with the specific needs of eachof these formulation characteristics and requirements. This applicatormay be made from elastic material with memory, meaning the ability toreturn to the shape in which it was molded, whereby when the productruns through the hole or slot, the elastomer memory effect results inthe passage being closed automatically once the internal containerpressure ceases. This process is normally called self-closing, with thiseffect in specific applicators, designed for each use in each region ofthe skin or body, allowing far safer applications, as it does not allowcontaminants to enter the external area or the external or internalparts of the container, thus avoiding contamination of the contents ofthe container, with this benefit being much sought after by thepharmaceutical, cosmetic, veterinary and even industrial markets,avoiding inflows of oxygen that could oxidize the product or result inother undesirable alterations to its formulation.

DETAILED DESCRIPTION OF THE INVENTION

As shown in these illustrations and their details, more particularlyFIGS. 1 to 9, this invention, being a VALVE MECHANISM WITH APPLICATORTIP FOR COSMETIC CONTAINERS, is comprised by the fact that it initiallyencompasses a lid-like mounting base (1) with external means (2) of leakproof attachment to the bottleneck (3) of a generally usual container(4) and with internal means (5) constituting a passage (6) for theproduct and that also constitutes an integral part of a valve (7) thatslides upwards and downwards and whose lower end is oriented to open andclose the passage (6), while its end is centrally housed in a sleeve (8)that internally receives the base of an applicator tip (9) from above,while the outer part receives the overcap (10) surrounding suchapplicator tip (9), the circular base is coupled to rotate in the sleeve(8), combined with an actuation mechanism (11) that is formed betweenthe two parts and constitutes the means for moving the valve upwards ordownwards (7) in order to open and close the passage (6) for theproduct.

The tip (9) is axially attached inside the sleeve (8) and thecorresponding part of the valve (7) whereby it may be twisted in bothdirections and with the mechanism (11) moving the valve upwards anddownwards (7) in order to open or close the passage (6).

The mounting base (1) is illustrated with details in FIG. 10, showingthat the external (2) and internal (5) means are formed by twocylindrical concentric sectors, in which the first constitutes acircular skirt with an internal lock (12) forming a leakproof attachmentto the corresponding lip (13) of the bottleneck (3) of a generally usualcontainer (4), while on the upper side projecting perpendicularlyinwards in the form of a blind flange (14) that is integrated with thesecond internal part (5) in the shape of a cup and whose diameter fitstightly into the bottleneck (3) like a stopper, with a sealing washer(15) and with the bottom of such internal part being pierced to allowthroughflow (6) and in the center of which there is an internal raisedcylindrical stopper (16) with a tapered tip (17), and with the externaldiameter of the part (2) also endowed with details for attachment to thebottom end of the sleeve (8) in the form of twist-prevention lock-lugs(18) and annular channels (19) that form an intermediate axial lockingstep (20).

The valve (7) is illustrated with details in FIG. 11, showing that itconsists of a vertical plunger (21) pierced lengthwise by a feeder tube(22) and whose upper end widens internally forms a first sealing lip(23), which also occurs with a lower end, although in this case acircular channel (24) results in two concentric sealing lips (25 and26), with the outer part sliding over the inner part (5) of the base(1), while the other lip (26) surrounds the end of the feeder tube (22)forming a tip penetrating the cylindrical stopper (16) that opens andcloses the feeder tube (22), with the external diameter of the verticalplunger (21) fitted with the longitudinal guide lugs (27) and tworadially opposed tips follower studs (28) that couple on to themechanism (11).

The sleeve (8) is illustrated with details in FIG. 12, showing that itinitially consists of the cylindrical skirt (29), with the wider bottomedge forming an external flap (30) that constitutes a slotback for thebottom end of the cap (10), while the inside of this flap has aplurality of grooves (31) and above them are two protuberant annularsectors (32), both attached to the base (1), where the grooves (31)engage with the anti-rotational locking lugs (18) and the twoprotuberant annular sectors (32) engage with the annular channels (19),comprising a coupling and permanent attachment between the twocomponents, thus avoiding the entire assembly coming loose or preventingany movement among the components (1), (4) and (8).

The upper part of the sleeve (8) is defined by two other internal,circular and concentric walls (33) and (34), with two channels (35) and(36) formed between them, within which is attached in a revolvingmanner, the lower end of the applicator tip (10), with the smallerdiameter inner wall (33) also constituting a slider housing for theupper end with the lip (23) of the plunger (21) and, to do so, alsoincludes two diametrically opposed keyways that constitute the surfacesof the cam (37) pierced by the radially opposed follower studs (28) thatare exposed in the channel or spacing (35) and in a position to couplewith the lower end of the applicator tip (9), whereby the latter canmove such tips over the surfaces of the cams (37) and thus move thevalve upwards or downwards (7), opening or closing it with 90° twists inboth directions and, to do so, the upper edge of the wall (33) of thesleeve (8) is lowered over a length of 180° (38) ending in rabbetbuffers and a light lock (39) that define the open and closed positions,with this rabbet (38) also forming a midline projection in the form ofvertical pin (40) that constitutes a buffer and limit on the 90°movement, open or closed, for the cap (10) which also has a lock on theprotruding inner edge (41) of the skirt (29) of the sleeve (8).

The applicator tip (9) is illustrated with details in FIGS. 13, 14 and15, showing that its lower end is defined by three concentric walls, aninternal wall which is a feeder tube and coupling (42), an intermediatewall (43) and an external wall (44), in which the first is shorter andhas two diametrically opposed keyways (45), while the other two are thesame height, with the lower edge of the external wall being slightly,forming a stopper step (46) and also between the two walls (43) and (44)there are two twist-control teeth (47). Such walls (43) and (44) areslid into the respective channels (35) and (36) of the cover (8),resulting in the steps (41) of the sleeve (8) and the step (46) of theapplicator tip (9) slotting into each other and with the teeth (47)positioned on the rabbet (38) of the wall (34) and finally the pins (28)of the plunger (21) are coupled to the keyways (45) on the internal wall(42). In this position, such applicator tip (9) cannot move axially,although it is free to slide and twist in this both directions, whichare the opening and closing movements, both with a radius of 90° andlimited by the teeth (47) and the vertical pin (40); concomitantly, theplunger (21) is twisted as its pins (28) are inserted in the keyways(45) of the applicator tip (9) and consequently the cam (37) moves thevalve upwards or downwards (7), allowing the inward or outward movementof the stopper (16) in the passage (6) and thus opening or closing suchvalve (7).

As shown in FIG. 16, in the upper edge of the cylindrical skirt (29) ofthe sleeve (8) a vertical indicator projection (48) faces the outside ofthe base of the applicator tip (9) and is aligned alternately with thetwo open and closed indicator buffer marks (49).

As shown in FIGS. 17 and 18, the upper end of the applicator tip (9)which extends in a shape similar to that of the tip of the forefinger,constituting an elliptical tip whose longest axis is positionedvertically, constituting a hollow part in the form of a casing (50) thatis slightly recessed in the rear wall (51), while its front side forms asmall open compartment (52), with the feeder tube formed by the wall(42) opening into its lower part and with this open compartment borderedby a double wall (53), forming a recessed border that constitutes anouter casing (54) and housing between the walls (55), both for holdingthe leakproof elastomer cap (56), whose front part is padded andfinger-shaped, embossed in a manner defined by a set of concentricelliptical protuberances (57) and with a small slit valve (58) in thecenter thereof that releases the product, while on the rear side, suchelastomer cap has a similar shape defined by walls (59) and (60) that isheld in position between and on the details (53), (54) and (55) of thecasing (50), whereby the compartment (52) of the casing serves as adelivery pouch for the product to be applied, which occurs only whenlight pressure is created in this inner part by pressing the container(4). Under these conditions, this pressure increases against the innerside of the cap (56) imposing demands on its elastic characteristics, atwhich time the slit valve (58) is forced open, although only narrowly,to the extent that a desired quantity of the product is released ontothe fingertip-shaped surface (57) and when the desired quantity has beenestablished, pressure is no longer applied to the container (4) and theelastic memory of the cap (56) completely closes the slit valve (58),keeping the applicator tip (9) properly closed, with a product insideready for a new operation.

Still with regard to FIG. 17, the tip (9) includes anatomical recessedlateral grips (61) offering access for the tips of the thumb andforefinger, making it easier to twist such tip (9).

The applicator tip (9) described above features construction details andan anatomical shape that work together to ensure a specific applicationof the product on the user's skin, particularly around the eyes,principally products defined generically as cosmetics, although thisalso includes drug products applied in the same areas around the eyes.

FIG. 19 shows an assembly modified to receive an anatomically differenttip, designed for other parts of the body, particularly those related tothe lips, although this shape for this region is more versatile and mayalso be used in other areas, principally on the face. This modifiedassembly has almost the same parts as already described, namely themounting base (1) which presents the same details for leakproofconnection to the bottleneck (3) of a generally usual container (4) andwith internal means constituting a passage (6) for the product and alsoconstitutes an integral part of the valve (7) moving upwards anddownwards and whose lower end is oriented to open and close the passage(6), while its end is centrally housed in a sleeve (8) that internallyholds the base of the modified applicator tip (61), while the outer partreceives the overcap (10) surrounding such applicator tip (61), thecircular base is coupled to rotate in the in the double sleeve (8),where an actuation mechanism (11) is formed by the two parts,constituting the means for moving the valve upwards or downwards (7) inorder to open and close the passage (6) for the product, similar to theprevious assembly.

The modified applicator tip (61) is also axially attached inside thedouble sleeve (8) whereby it may be twisted in both directions and withthe mechanism (11) moving the valve upwards or downwards (7) in order toopen and close the passage (6).

The modified applicator tip (61) is presented in greater detail also inFIGS. 20 and 21, showing that its upper end consists of two prolongedconcentric wall sectors, one internal (62) and one external (63), withthe former being an extension of the feeder tube and coupling (42),whose outer is surrounded by a spacing (64) and also has semicircularteeth (65), one on each side, above which is located an annular recess(66), which is repeated (67) at the top of the inner extension (62),which constitutes the sealing point, while the previous details (64),(65) and (66) form the coupling point for the lower cylindrical part ofan elastomer tip (68), whose upper end is cylindrical (69) and whose topis slanted, constituting an application surface (70), in the second ofwhich is a slit valve (71) that releases the product, while the lowerpart of such tip is tubular, with a slightly narrower outer diameterthat forms a step (72), which also occurs with the inner diameter,although the cross-section of the inner step is shaped like the topsealing ring (73), below which the inner diameter includes an annularprotuberance (74) and finally the lower edge extends in the shape ofdiametrically opposed hooks (75) that slot into the teeth (65) when thelower cylindrical part of the elastomer tip (68) is introduced into thespacing (64), where another coupling occurs when the annularprotuberance (74) slots into the annular rabbet (66) and at the sametime the sealing ring (73) fits into the top annular channel(67).

Similar to the previous tip, the pressure against the inner surface (70)imposes demands on its elastic characteristics, at which time the slitvalve (71) is forced open, although only narrowly, and just enough for adesired quantity of the product to be released on the surface (70) andwhen the desired quantity has been established, pressure is no longerapplied to the container (4), with the elastic memory of the tip (68)completely closing the slit valve (71) and keeping the tip (68) properlyclosed, with a product inside ready for a new operation.

Pursuant to the matters set forth above, it may be noted that theassembly in question materializes the above-mentioned advantages,including functioning of the valve points (7) and (58) or (71), oneactivated manually and the other functioning automatically, togetherwith the first one. FIG. 22 illustrates the first valve point in theclosed position, defined by the plunger (7). In this position, suchplunger is in its lowest position and consequently the stopper (16)enters into its feeder tube (22) and establishes a leakproof seal thatdoes not allow the product to run from the container (4) to the insideof the of the applicator tip (9). It opens only when such applicator tip(9) is twisted. At this time, as shown in FIG. 23, the mechanism (11)defined by the pins (28) of the plunger, the cam (37) and the rotatingbase of the applicator tip (9) simultaneously pulls such pins (28) tothe upper part of the surface of the cam (37), whereby the plunger (7)moves upwards and its lower end models out of the stopper (16), exposingthe feeder tube (22); in this condition, when the container (4) ispressed, the product flows into the applicator head (9). At this point,once filled, if pressure is maintained on the container (4), the productbegins to press against the wall of the elastomer cap (56), formingcontrolled internal pressure that is sufficient to gradually open theslit valve (58), allowing the controlled flow of the product that inturn accumulates on the surface (57). When the user releases thepressure on the container (4) the product concomitantly ceases to flowinto the applicator tip (9) and the internal pressure equalizes with theexternal pressure, and the elastic memory of the cap (56) allows theslit valve (58) to close again. Once this occurs, the user then twiststhe applicator tip (9) in the opposite direction, allowing the plunger(7) to return to the closed position.

The product accumulated in the elastomer cap (56) is applied with greatcomfort, as this part of the cap is soft and padded, like the tip of aforefinger, ensuring extremely easy application of the product to theskin.

The user may thus keep the plunger (7) in the open position whileapplying the product of the skin, or may leave the plunger (7) in theclosed position, after selecting the desired quantity of the product.This situation allows excellent control of the applied product.
